Removed obsolete pysqlite documentation.

These steps are no longer needed as of pysqlite 2.7.0.

-If you've decided to use a :ref:`newer version of pysqlite2
-<using-newer-versions-of-pysqlite>` instead of the ``sqlite3`` Python stdlib
-module, then you need to make sure it can load external extensions (i.e. the
-required ``enable_load_extension`` method is available so ``SpatiaLite`` can be
-loaded).
-
-This might involve building it yourself. For this, download pysqlite2 2.6, and
-untar::
-
-    $ wget https://pypi.python.org/packages/source/p/pysqlite/pysqlite-2.6.3.tar.gz
-    $ tar xzf pysqlite-2.6.3.tar.gz
-    $ cd pysqlite-2.6.3
-
-Next, use a text editor to edit the ``setup.cfg`` file to look like the
-following:
-
-.. code-block:: ini
-
-    [build_ext]
-    #define=
-    include_dirs=/usr/local/include
-    library_dirs=/usr/local/lib
-    libraries=sqlite3
-    #define=SQLITE_OMIT_LOAD_EXTENSION
-
-or if you are on Mac OS X:
-
-.. code-block:: ini
-
-    [build_ext]
-    #define=
-    include_dirs=/Library/Frameworks/SQLite3.framework/unix/include
-    library_dirs=/Library/Frameworks/SQLite3.framework/unix/lib
-    libraries=sqlite3
-    #define=SQLITE_OMIT_LOAD_EXTENSION
-
-.. note::
-
-    The important thing here is to make sure you comment out the
-    ``define=SQLITE_OMIT_LOAD_EXTENSION`` flag and that the ``include_dirs``
-    and ``library_dirs`` settings are uncommented and set to the appropriate
-    path if the SQLite header files and libraries are not in ``/usr/include``
-    and ``/usr/lib``, respectively.
-
-After modifying ``setup.cfg`` appropriately, then run the ``setup.py`` script
-to build and install::
-
-    $ python setup.py install
